Definitions

• Prac-- of the type in which the electrolyte contains such tically this is the case if the said amount is about ions as are liable to be transformed into hydrox- 50 grammes per 100 cubic centimeters of the ides and to be deposited in this form on the posifinished oxygen transmitting positive electrode tive electrode thus tending to clog the pores of (without its terminal).
• the said positive electhe said positive electrode, and in which the positrode is manufactured by thoroughly mixing fine tive electrode is depolarized by the oxygen of air crystalline sal ammoniac with the active carbon, contained therein.
• the said electrolyte contains adding thereto a slight amount of the electrolyte,
• the positive electrode may consist, for exincrustation of the electrode on the surface thereample, of a porous body of active carbon having Within the Same are P ed. an excess of air.
• I add a I claim: comparatively high proportion of sal ammoniac 1.
• trode is such that there is always an excess of sal 2.
• Thejgherein described galvanic battery comprising a positive electrode of the type in which depolarization is effected by the oxygen of air contained within the electrode, a negative electrode, and an electrolyte containing a manganese salt, in which the said positive electrode contains solid sal ammoniac in an amount such that, with the manganese-ion concentration corresponding to the intensity of the discharge current and the duration of the discharge occurring in service, precipitation of manganese salt on and within the positive electrode is prevented.
• the herein described galvanic battery comprising a. positive electrode of the type in which depolarization is effected by the oxygen of air contained within the electrode, a negative electrode, and an electrolyte containing such metal ions as are liable to be transformed into hydroxides and to be deposited on the positive electrode, in which the said positive electrode contains solid monomethylaminchlorohydrate in an amount such that, with the metal-ion concentration corresponding to the intensity of the discharge current and the duration of the discharge occurring in service, precipitation of metal salt on and within the positive electrode is prevented.
